CHARLES LYNCH, OF CHICAGO, ILLINOIS.

DUMPING-WAGON.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed April 26, 1910. Serial No. 557,806.

To all whom it may concern:

Be it known that I, CHARLES LYNCH, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

The purpose of my invention is the provision of an improved dumping wagon having a box or body-portion with trunnions at its ends mounted in bearings on the wagon-frame and in which they may be turned so that the contents or load of the box can be discharged at either side. The bearings which support the trunnions are open at the top, permitting the box with its trunnions to be lifted bodily by any hoisting means, such as a crane. This box or load receptacle is made in two parts hinged together at the top, and is provided on its ends and sides with means for attaching hoisting and dumping chains or cables, and it is also provided with a hasp or similar means on one or both ends to fasten the parts together in order to prevent the box from opening up and unloading its contents when not desired. If the load is to be dumped through the wagon-frame or directly beneath the running gear, the hasp is released, so that when the box is raised it will open and empty its contents. The wagon is equipped with mechanism for turning the box upon its trunnions in order to dump the load at either side of the wagon, and is also supplied with one or more catches operated by foot or hand to prevent the box from turning on its trunnions except at the proper time.

My invent-ion, in its preferred form, is illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation of my improved dumping wagon. Fig. 2 is a top plan view of the same. Fig. 3 is a rear end elevation of the same. Fig. 4: is a view similar to Fig. 3, but shows the body or box of the wagon turned on its trunnions so as to discharge its load at one side; and Fig. 5 is a vertical section of the rear end of the wagon, on an enlarged scale, on the line 55 of Fig. 3.

Referring to the drawings, the wagon includes the usual forward and rear wheels 10 and 11, respectively, and a reach-pole 12 connecting the front and back portions of the running gear. Above the rear axle 13 is provided the usual bolster which, in the present instance, is composed of a series of planks 15 superposed on each other and secured to each other and to the axle 13 by upright angle-bars 16 bolted to and across the several parts. On the inner side of the bolster thus formed is attached, by means of bolts 17, a vertical plate 18 notched at its top at 19 to receive the rear trunnion of the box or body hereinafter described. The front bolster 14E is similarly built up or raised, but the angles which correspond to the angles 16 do not extend below the lower edge of the bolster, and to the inner side of said bolster is attached a notched plate 20 similar to the plate 18, the forward trunnion of the box being adapted to fit therein.

The box or load-conveying receptacle consists of two mating parts 21 and 22 open at the top and also hinged together at the top at their respective ends at 23, the upper edges of the sides of said receptacle and the hinges 23 having loops or rings 24 and 25, respectively, attached thereto and constituting means for securing to the box dumping and hoisting chains or cables 26 and 27 respectively.

At the forward part of the wagon is the usual seat 28 mounted on the support29 and a foot-rest 30, as shown in Figs. 1 and 2. On each side of the wagon is a bell-crank lever 31 pivoted at its elbow at 32 t0 the built-up front support of the frame, each lever having a catch 33 adapted to engage the bottom of the load receptacle or box and having at its forward end a plate portion 84:, which affords means of actuating the lever by the drivers foot. Secured to each side of the support 29 is a ratchet-bar 35 with which a projection 34' on each lever is adapted to cooperate to hold the catches in such position that they will prevent the box from turning on its trunnions. Each trunnion consists, as best shown in Fig. 5, of a stub-shaft 36 having spaced collars 37 and- 38 adapted to be disposed on opposite sides of the notched bearing 18 or 20. The stubshaft 36 of each trunnion has rigid therewith a plate or base portion 39 bolted to half of the split box, the shafts 36,when the box is prevented from opening up except" when it is desired to discharge the load centrally beneath the wagon-frame, or at a point remote from the latter by raising the box by means of suitablehoisting means.

concentrically arranged with respect to the rear trunnion shaft 36 are two half gears 43 attached to the two portions of the box.

Bolted to the inner surface of the rear bolster is a bracket 44 (Fig. 5), in which is rotatably mounted a shaft 45, which extends rearwardly through an opening in the bolster. Atthe forward end of this shaft there is provided a pinion 46 meshing with ates a pinion 48 rotatably mounted below the shaft 45. The shaft or axle of the pinion 48 is provided with a protruding squared portion 49 upon which a wrench is adapted to be placed to operate the gears and turn the box or load receptacle upon its trunnions. K

The operation of the device is as follows: After the box has been loaded and lowered upon the wagon-frame so that its trunnions rest in the bearing plates 18 and 20 and the catches 33 have been actuated so as to engage the under surface of the box to prevent the same from turning over during transit,

1 the wagon is driven to the place where it is desired that the load shall be discharged. The unloading may be accomplished in several ways. By applying a wrench or crank to the projection 49 the loaded box may be turned by the gearing sidewise in either direction so as to throw its contents out to either side of the wagon-frame, the catches 33 having been previously removed. Where the load is to be dumped either directly be neath'the wagon-frame or at some distance therefrom, this is done by attaching the hoisting chains 27 to the fastenings 25 on the hingesof the box and also attaching the dumping chains 26 to the fastenings 24 on the sides of the box; then raising the box by the chains 27 releasing the hasps, and then transferring the weight to the dumping chains 26 which causes the box to automatically open and discharge the contents. Or, the chains 27 may be dispensed with and the chains 26 used as both hoisting and dumping chains. Where the load is to be discharged at a distance from the wagon, I prefer to employ both the chains 27 and 26,

since there is less danger of accidental premature opening of the box before the place of delivery is reached when the load is sustained in transit by the chains 27.

Obviously the minor details of the wagon may be varied without departing from the substance of the invention as defined in the following claims. For example, other fastening means than that shown may be employed. for uniting the two sections of the box, and instead of a split gear I may use a whole gear bolted to only half of the box but overlapping the other half so as to be centrally disposed and concentrically arranged with respect to the rear trunnion.
